hey guys i have recently aquired a used blueridge spa by jacuzzi m/y 2000. it wasnt working when i got it from friends who had gotten a new tub. they replaced the circulator pump, pressure switch. they had been taking advice from a tech at imperial spa, the last thing was to replace the circuit board which they opted not to because of the new tub. so we got it and i got the new board and replaced it.

now to my problem, the topside flashes "ps1" and only test fires the circ pump. it will do this 3-4 times then stops and needs resetting. the circ jets do pump water when running. not sure where to go from here. thanks for the help.
